TECWERK Solid Carbide Roughing End Mill NR-UNI Ø20 mm, TiAlN, 4 flutes

the TECWERK Solid Carbide Roughing End Mill NR-UNI Ø20 mm is a long-version roughing cutter engineered for high stock removal in steel, cast iron and non‑ferrous metals, thanks to its TiAlN coating and specialised roughing geometry

• TiAlN coating for high thermal resistance
• Solid carbide construction for rigidity
• 50 mm effective length for deep-pocket work

Faster roughing with controlled vibration for higher throughput

The long-version roughing cutter combines a special roughing profile with four flutes and a 45° helix to accelerate material removal while limiting chatter. The TiAlN coating offers elevated thermal resistance and a hard, wear‑resistant surface, which reduces flank wear under heavy cuts. As a result, the tool sustains higher metal removal rates with stable cutting forces, improving cycle times on batch and serial production while maintaining dimensional reliability.

Versatile suitability across common workshop materials

Designed as a universal, fine‑grain solid carbide tool, this cutter is rated very good for steel, non‑ferrous metals and cast iron, with conditional suitability for stainless and special alloys. The combination of positive rake geometry and the roughing profile enables efficient chip evacuation and consistent cutting behaviour across a range of workpiece materials, making it a practical choice for mixed‑material production environments that demand repeatable, high‑volume roughing.

Toolholder compatibility and runout reliability for precise machining

The cutter features a cylindrical shank to DIN 6535 HB with a 20 mm shank diameter and h6 tolerance, ensuring secure clamping and minimal runout in standard toolholders. The precise shank tolerance and the 20 mm body diameter provide predictable concentricity, which supports repeatable pocketing and slotting operations and simplifies setup in automated tool magazines.

Geometry and length tailored for deep pockets and stepped features

With an effective cutting length of 50 mm and an overall length of 104 mm, the tool suits deep‑section roughing and stepped machining where reach and rigidity must be balanced. The neck relief of 19.5 mm reduces friction in confined geometries, while the 45° protective chamfer and long profile maintain edge strength during interrupted cuts, so the cutter copes with entry impacts and pocket walls without rapid edge degradation.

Industrial readiness and process reliability

Manufactured as a long, four‑flute roughing end mill with a positive rake and a specialised chip‑breaking geometry, the tool is optimised for vibration‑reduced cutting and robust tool life in continuous production. The combination of solid carbide, TiAlN coating and DIN‑based shank standards delivers a balance of rigidity, heat resistance and interchangeability that supports standardised workflows and predictable maintenance intervals.
